Then there are the few who do make honest criticisms of work.  

The artist will then request that the forum moderator removes the offending comment.

All the friends of the artist who see the comment before it is removed rush over to the infidels gallery and post rude and nasty comments on any images they may have uploaded, regardless of the quality, as payback for him/her hurting their poor artist friends feelings.

The exception, of course, being those artists in the Critique Group who truly want help to improve their talent
